Write the equation of the line that is perpendicular to the line 3x + y = 7 and passes through the point (6, −1).

y = one thirdx − 3

y = one thirdx + 17

y = −3x − 3

y = −3x + 17

what is the slope of a line perpendicular to y = mx?

anonymous · Answer

-3x?

anonymous · Answer

slopes have no variables, close so pls try again.  Also note the question was perpendicular slope.

anonymous · Answer

So -3?
